Last year, my team Codex won the hunt. The reward (punishment?) for winning is the responsibility to write the 100+ puzzles, (and meta-puzzles, and meta-meta-puzzles, and theme, and events) and to put on the whole event the following year.
So over the last year, I’ve worked with a huge group of folks to put together this year’s hunt which had a theme loosely based on The Producers. My own role was small compared to many of my teammates: I contributed to some puzzle writing and to a bunch of "test-solving" of candidate puzzles to make sure they were solvable, not too easy, fun, and well constructed. During the hunt, I visited competing teams, verified answer submissions, and took advantage of my jet-lag from my return from Japan on the day of the hunt to work the night shift distributing items to teams.
To get an idea of what the hunt is like, you can check out a puzzle I wrote for this years hunt. The solution is linked from the corner of that page.
